NAME

       zgz - Frankenstein's compressor

SYNOPSIS

       zgz [options] < file > file.gz

DESCRIPTION

       This program is an unholy combination of the BSD gzip program, a modified GNU gzip that supports setting an arbitrary file name and
       timestamp, and an old, rotting version of bzip2 that we dug up somewhere at midnight.  Only the bits to do with file compression were kept.

       There are many arcane options which aid pristine-gz(1) in re-animating files. Use --help to see all the gory details.

NAME

       pristine-bz2 - regenerate pristine bz2 files

SYNOPSIS

       pristine-bz2 [-vdk] gendelta file.bz2 delta

       pristine-bz2 [-vdk] genbz2 delta file

DESCRIPTION

       This is a complement to the pristine-tar(1) command. Normally you don't need to run it by hand, since pristine-tar calls it as necessary to
       handle .tar.bz2 files.

       pristine-bz2 gendelta takes the specified bz2 file, and generates a small binary delta file that can later be used by pristine-bz2 genbz2
       to recreate the original file.

       pristine-bz2 genbz2 takes the specified delta file, and compresses the specified input file (which must be identical to the contents of the
       original bz2 file). The resulting file will be identical to the original gz file used to create the delta.

       The approach used to regenerate the original bz2 file is to figure out how it was produced -- what compression level was used, whether it
       was built with bzip2(1) or with pbzip2(1).

       Note that other tools exist, like bzip2smp or dbzip2, but they are said to be bit-identical with bzip2. Anyway, bzip2 looks like the most
       widespread implementation, so it's hard to find bzip2 files that make pristine-bz2 fail. Please report!

       The deprecated bzip1 compression method hasn't been implemented.

       If the delta filename is "-", pristine-bz2 reads or writes it to stdio.

OPTIONS

       -v  Verbose mode, show each command that is run.

       -d  Debug mode.

       -k  Don't clean up the temporary directory on exit.

       -t  Try harder to determine how to generate deltas of difficult bz2 files.

ENVIRONMENT

       TMPDIR
	   Specifies a location to place temporary files, other than the default.
